An efficient and mild copper-mediated reaction for the direct perfluoroalkylation and difluoromethylation of indoles with perfluoroalkyl halides and ICF2COOEt to produce 2-substituted indoles was developed. Both free indole derivatives and N-substituted indole derivatives could be used in this process to obtain the desired products in moderate to good yields.
An efficient and general process is reported for the photoinduced, copper-catalysed direct perfluoroalkylation of C–H bonds in a broad range of heteroarenes with commercially available perfluoroalkyl iodides. This redox neutral process is simply based on the use of [Cu(bcp)DPEPhos]PF6 as the photoredox catalyst in the presence of potassium acetate and smoothly operates at room temperature.

An efficient process for the copper-catalyzeddirect perfluoroalkylation of C−H bonds in heteroarenes with commercially available perfluoroalkyl iodides is reported in this work. This reaction is based on a simple combination of copper(I) iodide and phenanthroline enabling the easy reduction of perfluoroalkyl iodides to the corresponding radical species that add to a wide range of heteroarenes.
